JSON 战斗策略缺少 Info 节点

Error message

JSON 战斗策略缺少 Info 节点

What it means

Thrown by JsonCombatStrategyParser.Parse when the deserialized strategy object is non-null but its Info property is null. The Info node is required — it contains strategy metadata (name, etc.). This means the JSON object exists but lacks the 'Info' key or it was explicitly set to null.

Solutions

1. Add an 'Info' object with at least a 'Name' property to the JSON strategy.
2. Use the documented JSON strategy schema/template as a starting point.
3. Example: "Info": { "Name": "MyCombatStrategy" }.

Example fix

// before (missing Info)
{
  "Actions": [ { "Name": "a1", "Index": 1 } ]
}

// after
{
  "Info": { "Name": "MyStrategy" },
  "Actions": [ { "Name": "a1", "Index": 1 } ]
}

// Pre-check for the Info node using a lightweight parse
using System.Text.Json;

var doc = System.Text.Json.JsonDocument.Parse(json);
if (!doc.RootElement.TryGetProperty("Info", out _) || doc.RootElement.GetProperty("Info").ValueKind == JsonValueKind.Null)
{
    throw new ArgumentException("策略缺少 Info 节点");
}

try
{
    var strategy = JsonCombatStrategyParser.Parse(json);
}
catch (InvalidOperationException e) when (e.Message.Contains("缺少 Info 节点"))
{
    Logger.LogError("策略缺少 Info 节点，请添加 Info 对象");
}

When it happens

Trigger: The JSON file has an 'Actions' array but no 'Info' object, or 'Info' is present but set to null. For example: `{ "Actions": [...] }` without an Info key, or `{ "Info": null, "Actions": [...] }`.

Common situations: User creates a strategy file from a partial template that omitted the Info section, or deletes the Info block while editing. The Info node carries the human-readable strategy name used in logs.
